and" theycarton is.'partl'lally.\` opened. as shown in 3 Fig. 11 to be engaged by the feed slides or members 26 slidable in the slideways 21.

The slides 26 are reciprocated in their ways by the rocker arms 28 on the rockshaft 29, the rocker arms being made up of telescoping sections 3|! and 3|; the sections 30 are secured to the rockshaft 29 while the sections 3| are secured to the slides. The rockshaft is actuated from the main drive shaft 32 which is provided with a cam member 33 connected by the link 34 to the arm 35 on the rockshaft 29 (Fig. 3). The drive shaft 32 is driven by a chain 32| through a reduction gear 322 by the motor 323.

The cartons are advanced by the slides to the position shown in Fig. 2 with the extended cover 8 engaging the stop 36. With the cartons in this position they are engaged by the erector arms 31, there being three such arms in the embodiment illustrated. These erector arms 31 are mounted on the common rockshaft 38, the table being provided with slots or elongated openings 39 through which they swing into engagement with the carton positioned as shown in Fig. 2; the carton is engaged and the walls and bottom members swung to erected position as shown in Figs. 6 and '1. Certain of the successive steps are illustrated in these figures. The rockshaft 38 is provided with a crank arm 38| having a cam follower 382 thereon coacting with the cam 383 on the periphery of the cam member 33. The faces 40 of the erector arms 31 are designed to perform certain functions or steps in the erection of the cartons. These faces are provided with V-shaped 4notches 4| which engage the trailing edges of the cartons as they are delivered by the slides 26, the slides being notched at 42 to engage the trailing edges of the cartons as in the partially open position shown in Fig. 11.

Supported in opposed relation to the erector arms is a spreader abutment 43 having a curved face 44, As the erectors apply pressure to the trailing edge of the carton the upper edge of the front wall of the carton, or the upper wall as .appears in Figs. and '7, is forced against the curved face of the abutment 43 and slides upwardly along the same until it engages the overhanging ngers 45 which serve the purpose of stops and prevent the distortion of the walls of the cartons. The fingers are provided with downturned ends 46 which further prevent deforming of the cartons as they are opened or erected.

When the erector arms reach the position shown by dotted lines in Fig. 6 the continued thrust on the trailing edge swings the bottom members 5 of the carton downwardly on to the rearwardly diverging supporting surfaces 41 which extend from the V notches 4|. The erector members are provided with fingers 48 at their outer ends which coact with the outer surfaces 41 to provide V recesses 49, similar V recesses 50 being provided to receive the bottom edges of the inner walls of the carton. This prevents the carton from slipping out of place and it is completely extended and supported to permit the erection of the cross or transverse partitions. The abutment member is provided with a series of longitudinal recesses |44 which receives the top edge of the longitudinal partition 4 of the carton. f

While the carton is supported with its walls fully erected as shown in Fig. 7 the cross head 5| carrying a series of partial erector ngers 52 is actuated, there being two rows of these fingers corresponding to the two rows of cells. These ngers reciprocate through holes 53 in the forming head 43, see Figs. '7 and 8. The cross head 5I is mounted on the supports 54 for compound movement, that is, a lateral or front to rear movement to project and retract the fingers and also a longitudinal movement to impart a nal erecting movement to the transverse partitions and snap them into the openings in the bottom members. It will be noted that the fingers 52 have nose portions 55 which engage the transverse partitions as the fingers are projected and the cross head is shifted longitudinally, see Figs. 9 and 10. In Fig. 10 the fingers have been projected to the limit of their forward stroke and the partitions swung to substantially erected position.

The longitudinal movement of the cross head 5| indicated by dotted lines in Fig. 9 forces the partitions to the position shown in Fig. 10, in which position their lower ends snap through the openings 1 in the bottom members of the carton. In the embodiment illustrated the cross head is provided with rearwardly projecting arms 56 to which the actuating lever 51 is connected by means of the cross rod 56. This lever is pivoted at 59 and is actuated by the link 66 having a follower 6| coacting with a cam 62. The cross head is shifted longitudinally by means of the lever 63 which is pivoted at 64 and provided with a follower 65 coacting with the cam 66. The swinging end of the lever engages the slot 61 in the cross head. These cams are mounted on the shaft 32 so that the parts are actuated in timed sequence.

When the cartons have been fully erected they are engaged by the transfer slide 68 reciprocatingly mounted on the rod 69 supported at one side of the erecting table and at the top of the delivery chutes 16 (Fig. l). The cartons are delivered by the transfer slide to the chutes 16 which are provided with converging guides 1|. As the cartons are delivered to these chutes they are engaged for positive feed by the pushers 12 which are carried by the rod 13 which is in turn carried by the brackets 14 and 15 pivoted at 16, see Figs. 1 and 5. The operating link 11 is connected to the arm 18 on the rockshaft i6. The link 'I9 connects the cross bar 8U to the pusher slides 8| having a second pusher 82 mounted thereon so that the cartons are successively engaged and pushed into a semi-nesting relation on the table or chute 63; that is, they are nested to the extent that one carton overlies the extended cover of the preceding carton. The cartons may be removed from the table 83 for filling.

The transfer slide 66 is actuated in timed relation to the other mechanisms through the arm 85 on the rockshaft 86, the arm comprising telescoping sections 81 and 88 (Fig. 5). As the carton is shifted by the transfer slide it engages the stop 89 (Fig. 5) thereby allowing further movement of the transfer slide and disengaging it from the carton. The transfer slide is provided with a spring gripping finger 96. The rockshaft 86 is provided with arm 9| actuated by the link 92 provided with cam followers 93 and 9e coacting with the cams 95 and 96, respectively (Fig. 4). The operation is entirely automatic. The cartons are placed in the magazine 9 in upright position and are advanced to feeding position by means of the roller 91.

I have illustrated and described the invention in a very practical embodiment thereof. I have not attempted to illustrate or describe further modifications and adaptations which I contembeing provided with v-shaped notchesengaging the rear edge of the `partially opened carton and with V-shaped recesses at each Yside of said notches, surfaces of which supportingly engage the bottom members of the opened carton, a. rearwardly facing carton wall spreader abutment disposed in opposed relation to said erector arms as they are actuated, said abutment having a series of holes therein corresponding to the cells ofthe carton, and a cross head provided with a series of partition erecting lingers reciprocable in said holes in said abutment member.
